4 Claims.

This invention relates to a plow construction and it aims to provide one of the type usually drawn by a tractor, and which will work two Ways insure rotation of the wheels on horizontal axes,

regardless of the inclination of the land.

The more specific objects and advantages will become apparent from a consideration of the description following taken in connection with the accompanying drawings illustrating an operative embodiment.

In said drawings: I

Figure 1 is a plan view of a reversible plow construction according to my invention;

Figure 2 is a substantially central vertical ngitudinal sectional View through the plow construction of Figure 1;

Figure 3 is a vertical section of parts taken on the plane of line 33 of Figure 1;

Figure 4 is a horizontal section taken on the plane of line 4-4 of Figure 2;

Figure 5 is a fragmentary side elevation of the plow construction;

Figure 6 is a vertical section taken on the plane of line 13-45 of Figure 5;

Figure '7 is a vertical section taken on the plane of line 11 of Figure 6, and

Figure 8 is a vertical section taken on the plane of line 8-8 of Figure 6.

Referring specifically to the drawings wherein like reference characters designate like or similar parts, the machine has a skeleton metallic frame as at Ill, of any suitable shape supported by ground wheels at II and I2, mounted and opera-ole as hereinafter described, so that they may be adjusted to operate at different heights to maintain the frame I-Il level with respect to the ground. Extendin centrally and longitudinally of the machine and mounted by said frame In is a fixed shaft I3 having a returned end or terminal I4, which may be welded or otherwise secured to a. segment or plate I5 fastened to the adjacent end of said frame III.

Surrounding and journaled on the fixed shaft through and is also journaled in the frame It and plate I5. Tubular shaft I6 is also journaled in a bearing I1, within the frame I0 and supported from the latter by arms I8, bolted thereto as at I9. A collar I1 is clamped on shaft I6 to abut bearing I1.

An open or skeleton frame 29 is bolted in' any suitable manner as at 2|, to the hollow shaft I6 and is fastened by an arm 22 to; the same shaft. Such frame 20 has parallel beams 23 rigidly fastened thereto preferably removably as at 24, on opposite sides of the shaft I6, and preferably laterally disalined as shown in Figure 2. Each beam 23 at one end carries similar plow members 25, preferably removably fastened in place by bolts at 26. At the other ends, said beams 23 carry plows 21, preferably removably as by means of bolts 28. It will be seen from the drawings that the plows 25 are reversed to the plows 21 so that when one set of plows 25 is in operation, it will turn the furrow in the opposite direction to the turning by the other set of plows 21, when the latter are in operative position.

Said hollow shaft I6 is rotatable so as to arrange either set of plows 25 or 21 lowermost or in operative position. As shown in Figure 2, the plows 25 are in operative position but rotation of the shaft I6, would exchange the positions of the plows 25 and 21, disposing the latter in operative position. Rotation of the hollow shaft I6 may be effected manually through the .turning of a lever 29 fastened on such shaft I6 as at 39, in front of the plate I5 and the lever 29 is adapted to be locked or latched to said plate I5 in the position where the plows 25 are operative and in the position where the plows 21 are operative, through the engagement of a latch 3| with notches 32, provided in the peripheral edge of the plate or segment I5, 180, apart. Such latch 3| may be conventional, forinstance having a collar 32, slidable along the lever 29 and urged by an expansive coil spring 33 on such lever toward said segment I5.

At the rear end of the fixed shaft I3 is an abutment member 34, U-shaped in plan, as best shown in Figures 1 and 4, so as to have forwardly extending spaced arms 35. A suitable clamp 36 forms part of the abutment device 34 and it is rigidly but removably secured in place by a bolt 31 to the fixed shaft I3. Between such abutment device 34 and the arm 22 of frame 29, a bracket 38 is provided whichhas a sleeve 39, loosely mounted or journaled upon the tubular shaft I6. Such bracket 38 below tube 39 haswlalls I3 is a tubular or hollow shaft I16 which extends .55 4-9 which extend between the arms 35 with clea ance so that the bracket 33 may move on the shaft 39 to either side, to the extent permitted by the abutment arms 35. A rear or furrow wheel 4| is provided, being journaled as at 42 to a hanger or bracket 43, having an open or loop portion 44, surrounding the walls and being pivoted to a pin or shaft 45 mounted by such walls. In front of the clamp 36, a bracket 41 forms a bearing for the tubular shaft I6 and in combination with arm 22 positions the bracket, being mounted by an L-shaped arm 49 fastened to the frame 21) and by means of screws 50 to the bracket or bearin 41. It will be understood that the lever or bracket 44 is moved to press wheel 4I against the ground to elevate the frame, to provide clearance for reversal of the plows and that the wheel M is swung slightly either to the left or right and travels in a tilted position to one side or the other so as to travel in the furrow, according to the plow or plows'opcrating in the ground. The use of the wheel 4!, also enables me to locate the front wheels Iiand I2 farther from the plows, so that more weight of the machine will be imposed on the plows to facilitate engagement with the ground.

A lever 5! is pivoted at 52 to the bracket 49 adjacent the angle thereof and it has a chain or flexible connection 53 connected thereto and also connected to the top of the portion 44. Said lever 5i on the opposite side of the pivot 52 to .the flexible connection 53 also has a flexible or draw connection 54 consisting of a link 55 and a chain 5% connected thereto, for example, and extending to the front of the machine.

Reverting to the wheel Ii, it is journaled on an axle 5i of a hanger 58 including a horizontal sleeve 59, which is journaled' in a plate or bearing rising from one side of the frame 50. Disposed transversely of the frame and journaled to rock in the sleeve 59 and in a plate or bearing SI similar to that at 8B but at the other side of the frame E0, is transverse shaft or rod 62. Rod. 62 has a lever 63 rigidly connected to it and a link 64 is pivoted at 65 to said lever, having a hook 66 at its lower end, engaged with the hanger 58,v so that through the raising or lowering of the lever 63, the depth of the wheel II may be regulated, and the frame I5 correspondingly raised or lowered. Such lever 63 may be fastened in its different adjusted positions through the co-action of conventional latch mechanism iii thereon with a toothed segment 68, which is fastened to the adjacent end of the cross shaft 62.

The previously mentioned wheel I2 has a rim 69, spokes l0 and a hub ll. on. an axle I2 having an upwardly extending crank arm '53 which is pivotally suspended by a pin E4 on an arm '35 depending from a lever I6 pivoted at 11 to the frame It). An annular drum T8 at the inner edge thereof is welded or otherwise fastened to the spokes I0, concentrically of the wheel I2 and it has longitudinal corrugations or teeth l9 on the inner surface thereof.

An outer drum 88 surrounds the drum I8,-

Hub II is journaled drum and extends through an enlarged slot 89 in drum 88. Said lever 81 has enlarged ends 90 and SI located adjacent notches 99a and 9Ia in the periphery of drum 80.

The said transverse shaft or rod 62 has a depending arm or crank 94 which is slidably engaged in a bearing 95, fastened to the cap 9I. A collar 98 surrounds the crank 94 and a bell crank lever 97 is pivoted thereto at 98 to one end of which a link 99 is pivoted and which in turn is pivoted to a slidable element I09 mounted on the crank .34. Such element It! has an arm HII which is engageable against enlargement 90 and in notch 99a or in enlargement SI and notch E; la, according to whether wheel I2 is to be raised or lowered, and in either of which positions lever 811 will be rocked and pin 85 disengaged from teeth 79 to enable relative movement of the drums or parts adjustably mounting the wheel. Lever 9? may be actuated by a draw element such as a cable I06 fastened to the same at one end and at It? at the other end to the lever I5, the cable passing through a guide I08 on such lever. When the elevation of the wheel I2 is to be varied to regulate the level or position of the frame it, lever 91 is rocked in order to slide the arm IilI to rock lever 81 and engage the latch pintii with the teeth 79. whereupon the axle 12 will swing to the desired extent on the pin I4, following which, the lever 9! is released, slide ltd is restored by spring I03 to normal position and the arcuate rod 89 again restores the latch 83 out of engagement with adjacent teeth I9, the movement of the crank 94 having been accommodated in the slide mounted on the turnable cap 9|.

Attention is called to the fact that the draw means 54 at the rear end of the chain 56 is fastened as at I839 to the cross shaft 52. Thus whenever shaft 62 is rocked in connection with the variation in elevation of the frame II] or wheels II and E2, the draw member 54 will be drawn or paid out, with such movement effecting the lever EI and chain 53, and correspondingly or proportionately swinging the bracket 43 on the pivot 65 in order to raise or lower the wheel 45.

Attention is also called to the fact that two ,co'ulters are provided in advance of the plows as at I Hi, the same being journaled at III on the lower ends of standards I 52, detachably bolted as at H3, one on each of opposite sides of said frame Ii A draft tongue I I4 is fastened to a bracket i I5, in turn secured to the frame I5 and segment H5 at I it, to enable attachment of a tractor or other draft means thereto.

-Various changes may be resorted to provided they fall within the spirit and scope of the appended claims.
